vShear Displace¶

Adjust a vertex strip via horizontal shear (camera plane) with first-contact snap.

What is it?¶

Shears selected vertices horizontally in the camera view plane to align them with the line defined by two guide vertices: the anchor (second-to-last selected) and the destination (last selected). It preserves each vertex's screen-space height and displaces only along screen-space X. When the first vertex reaches the guide line, it snaps (with a green square indicator). Hold Alt to ignore snap.

Access and Shortcuts¶

Pie Menu: Edit Mode → vShear Displace
Operator: damtools.vshear_displace
Modal keys:
Mouse X/Y → Adjust shear amount
Shift → Fine movement
Alt → Bypass snap
Enter/Space/Left Click → Confirm
ESC/Right Click → Cancel (restore original coordinates)

Workflow¶

In Edit Mode, select 3+ vertices. The second-to-last is the Anchor; the last is the Destination.
Run vShear Displace.
Move the mouse to shear horizontally (camera plane). Vertices keep their screen-space Y; only X shifts.
When the first vertex hits the Anchor–Destination line, it snaps. A green square marks the snapping vertex.
Confirm or cancel.

Suggested GIF: selection → shear → snap with green highlight → confirm.

Parameters¶

Shear Amount (implicit): controlled by mouse movement; Shift reduces sensitivity.

Tips¶

Use Alt to temporarily pass through the snap.
For precise placement, zoom in and keep Shift pressed.
Works best when the camera is aligned with the intended working plane.

Known Limitations¶

Nearly horizontal or vertical guide lines may require finer mouse control; Shift helps.
Shear happens in view space; extreme perspectives can alter perceived distances.
